Bacteriophage interactions with mammalian tissue: Therapeutic applications

Area of Science:

• Microbiology
• Virology
• Human Health

Background:

• The human body hosts numerous bacteriophages (phages), bacterial viruses with significant roles in host interactions.
• Phages are increasingly explored for therapeutic applications, including engineered phage therapies.
• Understanding phage interactions with mammalian cells and tissues remains limited despite growing clinical interest.

Purpose of the Study:

• To review direct evidence of bacteriophage accumulation in various mammalian tissues.
• To highlight the unique ability of phages to traverse biological barriers.
• To discuss the relevance of phage barrier traversal to therapeutic applications.

Main Methods:

• Literature review of studies investigating bacteriophage presence and distribution in mammalian tissues.
• Analysis of experimental data demonstrating phage penetration of physiological barriers.
• Synthesis of findings related to phage-host interactions and therapeutic potential.

Main Results:

• Bacteriophages are found in diverse human tissues, including those previously considered sterile.
• Phages exhibit a remarkable capacity to bypass anatomical and physiological barriers in mammals.
• Evidence supports phage accumulation in tissues, suggesting active or passive transport mechanisms.

Conclusions:

• Phages possess unique capabilities to traverse mammalian biological barriers.
• This traversal ability is crucial for understanding phage-host dynamics and developing phage-based therapies.
• Further research into phage barrier-crossing mechanisms is essential for optimizing therapeutic strategies.
